I like Todd's questions, but I would slightly change how to go about the answers.

I believe that a better way to test the spark is without moving a wire. I keep a timing light handy and clip it to the center wire of the distributor cap. Use for timing, but great to see if you have the steady rhythm that you expect from a happy ignition system. An erratic pulse of light is easy to see and means there is something wrong. (and you can do the test quickly on the side of the road).

For checking fuel delivery, a clear fuel filter added at the carb fuel return line can be looked at quickly and if it's dry, something is wrong.

Both tests, at "starter speed" should show results. That's especially useful if you can compare what it's like when you are stalled on the side of the road to what it's like in the drive way.

I am rather fond of the glass fuel filters that can have the element replaced, but they can leak and be a fire hazard, so exercise some caution with them.
